Abstract The effects of TPAOH/SiO 2 , H 2 O/SiO 2 , SiO 2 /Na 2 O and SiO 2 /Al 2 O 3 ratios in the initial synthetic mixture on the crystallization of nanoparticles of ZSM‐5 zeolite under atmospheric pressure were studied. A Taguchi orthogonal experimental design with three levels of the above‐mentioned parameters was used to optimize the experiment parameters by the analysis of variances (ANOVA). Applying the Taguchi method significantly reduced the time and cost for optimization. The obtained products were characterized by scanning electron microscopy, X‐ray diffraction and FT‐IR spectroscopy. As a result of the Taguchi analysis TPAOH/SiO 2 followed by SiO 2 /Al 2 O 3 was the most influencing parameters for the synthesis of nanosized ZSM‐5 crystals.
